Oh my gosh, no internet.

So, you guys, last night when I checked the tubes not for the last time but for the very last time, everything was working fine.  I connected to Safari and my computer hummed like a busy, efficient bee.  Gmail, blog, Huffington--up-to-date and off to bed.  But this morning, the internet has stopped being my friend, as in our friend, and there are all sorts of errors and problems, and failures to connect.  

Failures.  To connect.  As in, my efforts to connect all failed.

Rebooting like a mad woman has done nothing.  I can't even isolate the problem:  the historian's laptop won't connect, not even with the ethernet cable, but I can't connect to singing son's wireless, so what is it? and why this sudden meltdown?  The thought of talking to some probably very hardworking IT guy on the phone to troubleshoot it all makes me simultaneously itchy and weepy and rage-y.  

I am not amused.
